# Convert Decimals to Percents

**Quick Method: move the decimal point 2 places to the right and add a "%" sign**

### Example: Convert 0.35 to percent

Move the decimal point two places to the right: 0.35 → 3.5 → 35.

Add a % sign: 35%

Answer **0.35 = 35%**

## Why

50 of these 100 squares are green, so \frac{50}{100} , or **0.5**, of the box is green.

And percent means "per 100", so **50% of the box** is green.

So** 0.5 (a decimal number) = 50%**

(the "%" tells you that there is a hidden "/100" there)

To convert from decimal to percentage, **multiply the decimal by 100**, but remember to put the "%" sign so people know it is per 100.

## The Easy Way

The easy way to multiply by 100 is to **move the decimal point 2 places to the right**. so:

From Decimal | To Percent | |

move the decimal point 2 places to the right, and add the "%" sign. |
